Is the corned beef hash still homemade here like it was when it was the Duchess Diner?

Yes. I have had the corned beef hash and it is delish.

I would like to thank Kathy for answering my question and I wonder why people answer my question by telling me they don't know the answer

I really don't know

I honestly don't know, but, I'd suggest calling there to find out if that's something you are interested in.
